14. Independent Product Description
This heavy‑duty marine reverse bevel gear is a reliable aftermarket replacement for high‑horsepower Tohatsu and Nissan outboard units, including 2006 MD115A, MD90B(AQ), NSD115A, NSD90B as well as 2003 M115A2 and NS115A2. It restores reverse‑gear function for heavily loaded lower‑unit transmission assemblies under salt‑spray marine surroundings.
Built from wear‑resistant quenched alloy steel, this component undergoes accurate CNC machining alongside thorough heat‑treatment steps. Its robust structure maintains stable rigidity under continuous high‑torque loads. Hardened gear teeth resist chipping and scuffing during frequent forward‑reverse gear shifts.
Every shaft‑hole measurement and spline dimension closely meets OEM tolerance benchmarks. Fitters can complete quick, exact installation, and no trimming or secondary rework is necessary.
This practical service‑grade aftermarket part resolves common gear‑case troubles such as reverse gear slipping, grinding gear noise, choppy power transmission and heavily worn‑down tooth surfaces. Swapping out the aged reverse gear restores stable reverse‑gear performance inside your outboard gear case. Be sure to refer to the official factory service manual for proper mounting and gear‑oil top‑up. Once assembled correctly, your outboard will deliver reliable power‑output performance on open water.
This part also can be used in the following motors:
